Technical field

This invention relates generally to will print image to combine to show the three-dimensional with or without movement with lens array (3D) image, and more particularly, to it is a kind of be suitable for based on the micro- of square, round, parallelogram or hexagon The array of lens is used together, to provide the enhancing 3D images with more complete volume and/or with multi-direction movement (imagery) method of arrangement and the imaging of pixel-map, offer pixel.

Background technology

Presently, there are it is expected to watch many applications for printing image via the array of lens.For example, anti-fake effort (effort) use of following security devices or element is often referred to:The security devices or element by lens array and by The image for being printed onto on the back side of lens array or being printed on the substrate of lower section or surface (for example, the scraps of paper or plastic sheet) Composition.Security element is displayed for hypograph:The image, which is selected as, to be unique and is to carry Security element Items be not counterfeit indicator.Anti-fake market just promptly increases in the whole world, wherein Security element is placed on extensively In the items of general (wide range), such as on currency (for example, on the surface of paper bill (paper bill), with side Helping prevents from replicating) and in the label (for example, showing the label on the clothing of authenticity) for retail product.

In this regard, moire pattern is in the array with round lens and the array with hexagonal array (or circle Shape and hexagon lens array) Security element in using for many years.Typically, the institute in the ink layer under these lens arrays The printing image of offer is small, fine image for the size of lens.Moire pattern is with secondary (secondary) The form for the pattern being obviously superimposed with vision is provided in printing image, and the pattern which is obviously superimposed is to work as table What two identical patterns superposition on face created when shifting or rotate on a small quantity each other simultaneously.

In such Security element based on moire pattern, in image some can with one to one in two axis Dimension lens it is printed compared to slightly more frequent or less frequent frequency, and some in image can be relative to that This is somewhat differently printed.Fig. 1 show using moire pattern amplification, the example components that may be used as Security element 100.Component 100 includes the lens array 110 being made of the column (or row) 112 side by side, parallel of round lens 114, and can To find out, row 112 are offset from one another (about 50%) so that adjacent lens 114 in row to being misaligned (for example, in next column Lens are placed in the gap between two lens in previous column).

Printing image 120 is provided at (flat at the back side of lens array 110 in the ink layer under lens array 110 On surface).It is being difficult to see in Fig. 1 the result is that the mistake of the depth of field is provided to viewer via the lens 112 of lens array 110 Feel, or image is moving in some cases feeling (movement of shown items or animation) amplification Mohr diagram Case.Typically, range of the thickness in each of lens 112 at 0.5/1000 to 5/1000 inch (or 12 to about 125 microns) In, and the frequency of these lens 112 in array 110 is approximately per inch 400 × 400 to more than 1000 × 1000.

It is forged although helping to reduce, it is anti-fake using having the moire pattern of amplification round lens array not enable completely Market is satisfied with.One the reason is that be limited using the effect that moire pattern may be implemented.For example, cannot take pictures and using not Your pattern shows 3D.Usually, moire pattern per inch in about 20 to 75 microns of focal length and an axis is more than 500 A lens are safe and/or anti-more than being used in the very delicate lens of the frequency of 250,000 lens per square inch In pseudo- industry.As a result, the image in lens array under lens is typically at least printed with 12,000DPI (dpi (dots per inch)) Brush, and even can be to be provided more than 25,000DPI.These microlens arrays are usually as in Fig. 2 with its array 210 Close nesting (nested) shown in element 200.Array 210 is used in the row 212 for deviating and being superimposed (for example, lens side by side 214 be expert in it is unjustified, and be placed as filling or being nested into the gap between two lens of adjacent column 212) in carry The hexagon lens of confession, to focus and amplify the image or moire pattern 220 in the ink layer of lower section.

A problem or problem using this array 210 and image 220, which are that element 200 is relatively easy, to be carried out reversely Engineering, which has limited its serviceabilities as Security element.Specifically, the pattern 220 under lens 214 can use cheap and hold The microscope easily obtained sees that this permission people determines the frequency of image and pattern.In addition, lens 214 can be cast and again Molding, this to print identified image and is successfully, reproduced element 200 (and then counterfeit currency or the label of product) Unique obstacle.Unfortunately, due to high-resolution laser and placing device (setter) and other printing progress, image is printed 220 become easier to complete.Typically, for element 200, lenticule is printed using embossing and filling technique, makes printing It is limited to a kind of color, this is attributed to the technique the fact being easy automatic pollution after a kind of color, and is also due to the work Skill is difficult to control the fact that spacing of the relative hue in embossing and filling printing technology to color.

Accordingly, there exist for lens array and printing image are combined (ink layer for including image/pattern) to show shadow The needs of the design of the component or element of picture and the progress of manufacture view.This improvement can allow to produce new security devices or Element, to be used together with other items with currency, label, credit/debit card, and these security devices preferably will It is more difficult to --- if not hardly possible --- replicate or copy.In addition, existing for following such security devices The demand of growth:The security devices using it is shown by it, such as float on focal plane and/or the image of following image (for example, more true 3D display) provides pleasantly surprised (surprising) or " factor (wow factor) ".

Invention content

Briefly, it is saturating in the array combined with the image to interweave with twin shaft to recognize that offer is then able to by inventor The different nestings of mirror may be beneficial.For example, lens can be the lens based on circle or square of its center alignment, make The parallel row and column forming array by lens is obtained (for example, not so that adjacent as seen in the array of Fig. 1 and Fig. 2 In the case that mirror is offset from one another).It is shot from according to along first axle (X-axis) and also along multiple viewpoints (POV) of the second axis (Y-axis) (take) printed text that the matrix of the frame of image is generated prints image.Frame interweaves in two directions, is arrived with providing The pixel-map of the lens of array.

More specifically, providing a kind of vision useful as the security devices on bank note, Product labelling and other objects Display module.The component includes the film of transparent material, and the film of the transparent material includes the first table of the array comprising lens Face and the second surface opposite with first surface.The component further includes the printing image close to second surface.The printing image Include the frame of the one or more images to interweave relative to two quadrature axis pixel (from use twin shaft interweave rather than as tradition The uniaxial file printing for interweaving generated in grating (lenticular) printing).The lens of array are nested in multiple parallel Row in, and the adjacent lens in the lens in the row of array can be aligned in the single row being expert at (for example, at some In the case of, it may be useful that adjacent lens, which do not deviate).

In order to provide lens array, lens can be based on circular lens, based on square or based on hexagon Lens.The lens of array are provided with the 200LPI (or higher LPI) measured by two quadrature axis the two.Lens can respectively have There is the focal length less than 10/1000 inch.In some embodiments, frame includes respectively the different points of view of one or more images (POV).In this case, frame includes along image of the first axle from least three POV in two quadrature axis, and frame Further include additional from corresponding with each POV in three POV at least two along the second axis in two quadrature axis POV image.

In the assembly, printing image can be adapted to be so that the image shown from normal POV includes the first of symbol The second set of set and symbol, and in the image shown when component is rotated from normal POV about first axle, symbol First set and the second set of symbol move in the opposite direction.In addition, printing image can be adapted to be so that working as In component image shown when being rotated from normal POV about the second axis orthogonal with first axle, the first symbol and the second symbol It is moved on the single direction orthogonal with the second axis.

In other assemblies, printing image can be adapted to be so that the image shown from normal POV includes the of symbol The second set of one set and symbol, also, in the image shown when component is rotated from normal POV about first axle, The first of symbol and the second set of symbol can be moved on the single direction parallel with the first axle of component.In this of component In kind embodiment, printing image, which can be adapted to be, to be made when component is revolved from normal POV about second axis orthogonal with first axle When turning in shown image, the first symbol and the second symbol move on the single direction parallel with the second axis.

Another visual effect is realized in the other embodiment of component.Specifically, printing image may include wallpaper figure Case (for example, with icon, mark and other symbols) and superposition pattern.Then, printing image may include the pixel of mapping, make Wallpaper pattern from multiple POV it is visible (when component rotates relative to the sight of viewer/tilt to different angle when), and fold Add pattern that there is visual range different on multiple POV.For example, different visualitys may include:Along the normal POV of component Superposition for viewer not visible (or only faint visual), from normally increasingly rotating or tilt component is (one far In the case of a little in any direction) so that the darkness of superposition pattern or brightness increase, until completely it is visual (or such as relative to Color its possible dark or bright to the greatest extent at the more normal more extreme angle of angle in the range of 45 to 60 degree etc. It is bright).

Ink layer 320,420 is adapted or is designed as to be used together with lens array 310,410, has to provide or does not have There is the total volume 3D display image of multi-direction movement or animation.Specifically, it is similar to raster image, in X-axis and then The interlaced video in Y-axis, to create total volume 3D interlaced videos.There is lens 314,414 point for viewer to focus, and By (via image of the lens array 310,410 according to the light reflected from ink layer 320,420) institute of viewer's viewing The image obtained is all 3D rendering in all directions, regardless of the viewpoint of viewer.

At this point, by being arranged using the pixel-map in the ink layer 320,420 combined with lens array 310,410 It is carried out relative to using effect caused by the conventional component (component shown in referring to Fig. 1 and Fig. 2) based on moire pattern It may be useful to compare and compare, wherein having the effect of being listed below:(1) More and the pixel-map according to this specification The two is provided which to float;(2) flying height is limited in 100% in the case of using moire pattern, and uses and reflected based on pixel 150% floating may be implemented in the embodiment penetrated;(3) two kinds of technologies are provided which that the directions 1- move;(4) only with pixel-map skill Available/achievable on-off of art;(5) it is also that can get animation only with the embodiment based on pixel-map;(6) More is used Pattern cannot provide amplification, but pixel-map, which may be used, can provide amplification;(7) described herein be based on can only be used The embodiment of pixel-map provides true 3D;(8) be also can only using this specification based on the embodiment of pixel-map come Realize movement in the opposite direction;(9) images upwards/side is can only be by using the embodiment based on pixel-map Come another effect realized;And (10) are only capable of obtaining entirely by using lens array and pixel-map teaching herein Volume 3D.As two kinds of technologies these effects or aspect it is some or all of as a result, the security devices based on moire pattern It is easy to carry out reverse engineering, and the security devices based on pixel-map are it is not possible that or hardly possible carry out reverse engineering.

With to lens array general understanding and the lens array understood configuration in the case of, discussion is based on Pixel arrangement, imaging and the mapping of lens round and based on square are (for example, the ink layer of component shown in Fig. 3 A to Fig. 4 B Design) may be useful.Traditional raster printing (intertexture of the image for being used together with grating lens array is printed) Using the certain amount of file created from different points of view (or visual angle point), to obtain 3D effect.For example, by single plane Viewpoint be moved to the left or right, to create next viewpoint.Traditional raster printing also uses the different frame from image sequence, To create certain movements or animation or other visual effects.Once generating, then the set of frame or file is combined in intertexture text In part, grating lens array can be applied on it by being then printed on the back side of grating lens array or being printed to Substrate on.The process that definitive document is created from primitive frame is referred to as " interweaving " (for example, will print information striped and arrange To match the process of specific grating lens array to determining deviation).

Intertexture on traditional raster shape material only has there are one direction, and interweaves and depend on lens direction so that striped Change is horizontal or vertical.The process is combined frame so that observer can see according to lens direction and flatly Or the effect that vertically (but not being the two) acts on.Fig. 5 show acquisition from three different points of view 510,520 and 530 (such as- 45 degree, orthogonal and+45 degree etc.) viewing single image or scene 540 file set so as to the process that in press uses 500.Viewpoint 510,520 and 530 is the view obtained from Same Scene along trunnion axis or X-axis.The frame that is obtained from viewpoint regards Point 510,520,530 is slightly different, and is then combined in interleaving process.When the frame and grating material of the interlaced video When piece is combined and watched, which can generate depth perception or 3D effect.

As shown in Fig. 3 A to Fig. 4 B, it can be used in printing image in lens array based on round and square lens In row, and these lens can allow effect while effect is in two directions, for example, acting on horizontal and vertical side simultaneously Upwards.The fact that create visual effect in all directions also requires in the print being used together with round or square lens array More complete frame or view set from Same Scene are provided in map brushing picture (or ink layer).This point is recognized in inventor In the case of, inventor develops a kind of for being interleaved (or more accurately, to these frame set from single scene Pixel is mapped, arranged and is imaged) new process (being described below).

For example, based on annular, hexagon, type of parallelogram or circular lens array (compared to cylindrical lens or Elongated cylindrical mirror) allow a set not only with the viewpoint that can be used together as shown in Figure 5 with traditional raster lens, And also there are the different sets of the viewpoint from different height (or along vertical axis or Y-axis).Fig. 6 is shown for from field Scape 640 (it can be identical as scene/image 540) obtains the process 600 of additional frame or view.As indicated, from single scene Image 640 in obtain from three different points of view (for example, relative to being orthogonal to+45 degree of Y-axis, being orthogonal to Y-axis and opposite In Y-axis -45 degree etc.) frame 610,620,630.

One of main difference between presently described process and traditional raster printing is following facts:Viewpoint or and this Two or more set of the corresponding frame of a little viewpoints are combined in the image file for printing now.In other words, edge It vertical axis and is that viewpoint executes intertexture along trunnion axis.It means that instead of a sequence of interlacing frames, new intertexture Journey (or printed text generating process) is related to intelligence and maps frame corresponding with the different points of view taken along both X-axis and Y-axis Matrix.In this example, as shown in the diagram of Fig. 7 700, exist respectively contain three frames 712,714,716,722,724, 726,732,734,736 three set 710,720,730.This is considered each horizontal or X-axis viewpoint of selection (as schemed Shown in 5) and then generate two for single scene additional vertical or Y-axis viewpoint (as shown in Figure 6) (or vice versa It is as the same).

Fig. 5 to Fig. 7 provides simple example, but can utilize the viewpoint of many other quantity.For example, traditional raster prints Brush may relate to using with along corresponding 10 frames of 10 different points of view of X-axis (or Y-axis).On the contrary, presently described friendship It knits or image printing process will be related to each 10 set for having 10 frames by oneself so that the total quantity of frame provides the matrix of 100 frames.Root According to this description, interweaves or then printing process is related to that each of 100 frames are mapped and are imaged within a single pixel.

At this point, be more fully described X-axis and Y-axis pixel mapping and imaging with obtain can be printed with What one of (such as, as a part for security devices for currency or Product labelling) lens array of this description was used together Image file may be useful.The preferably matrix (for example, matrix 700 of the frame file of Fig. 7) of combined frames file, to give birth to At the file to be printed, and this document is when printed and when pre-defined/specific lens array is used together, can To generate desired visual effect.For example, if it is assumed that for each frame set using six frames (rather than as in Fig. 7 Three shown in set 710,720,730), then the matrix of frame will be that (wherein, frame number provides set number and the set Interior frame):

Frame 11 Frame 12 Frame 13 Frame 14 Frame 15 Frame 16 Frame 21 Frame 22 Frame 23 Frame 24 Frame 25 Frame 26 Frame 31 Frame 32 Frame 33 Frame 34 Frame 35 Frame 36 Frame 41 Frame 42 Frame 43 Frame 44 Frame 45 Frame 46 Frame 51 Frame 52 Frame 53 Frame 54 Frame 55 Frame 56 Frame 61 Frame 62 Frame 63 Frame 64 Frame 65 Frame 66

The first step in mapping/imaging can be that every a line of the frame from matrix is combined (for example, as used Vertical lens are such).In this way, it generates in X-axis from Same Scene but (comes from slightly different height or viewpoint From Y-axis) packed-pixel sequence.For example, combination may begin at and is interleaved to six frames of the first row from matrix, Six frames from the second row are interleaved, and so on up to for frame file (scene from different points of view Image) matrix each row there are an interleaved files until.Figure is named according to the sequence of the top-to-bottom from matrix As sequence may be useful, and the first interleaved files can be " IF 01 ", this be from the first row as a result, and according to This analogizes the 6th intertexture text until we have the 6th row from exemplary (but non-limiting) matrix provide above Until part " IF 06 " file.Fig. 8 shows the figure of the image of matrix 700 of the use from Fig. 7 in the row for matrix As 800.The destination file for providing image 800 is (the image striped of intertexture of slice 810 of each frame in particular row (stripe) or slice 810) combination.

Second step in mapping/imaging be the file (X-axis) of these vertical cartels is combined into one will be in press The definitive document used.Information that is useful or even needing is for concomitantly or simultaneously creating effect in the other direction A dropping cut slice for fruit.The second mapping process (level) is executed, but is made at this time using the vertical pixel file being previously generated Two-way (X-axis and Y-axis) frame is created to input.

In the second step it is desirable that:(1) pixel in file is hung down by previous defined same sequence Directly combine;(2) file is regenerated using the horizontal information according to (pursuant) pixel-map, and therefore creates print Brush file;And (3) the result is that the two-way pixel-map with whole 3D or movable information in both direction, which means that Instead of with striped or slice, definitive document have from the matrix with the frame similar mode arrangement in matrix with number According to square.About the Section 3, it may be important that it is noted that when with based on circle, hexagon, parallelogram or just When the lens combination of rectangular array, the image printed from this document will allow to realize/show any view to viewer, and To allow that movement is presented in any direction.

Fig. 9 show from from the second mapping/image-forming step final mimeograph documents export can print so as to based on The image 900 that is used together of lens array of circle, hexagon, parallelogram or square.In the final linear image 900 In, it can be seen that the intertexture in the vertical direction with slice/striped 912, and it can also be seen that there is slice/striped 914 Horizontal direction on intertexture.It decomposes and/or amplifier section 910 is for showing that two direction interweaves, and it is final that this is also shown " square " synthesis (composition) of printed text (two axis composition files) is useful (for example, with reference to square 916) 's.

Mapping and imaging can also be executed using both X-axis and Y-axis, to realize movement effects.It is printed in traditional raster In, design is the cycle (loop) obtained in the intertexture printing image with description or the frame sequence for providing movement.It is this " to follow Ring " concept is also useful for printing described herein, but again, using based on annular, hexagon, parallelogram Or the lens (or other lens arrays) of square, to handle the matrix of frame.In order to be followed in all directions Ring sequence should typically carry out permutation matrix in the following manner:Matrix each row and also in each line (line)/row Watch cyclic sequence simultaneously.For example, if the input for printing is the sequence of six frames, the matrix of 6 × 6 frames can be arranged It is classified as:

Frame 5 Frame 6 Frame 1 Frame 2 Frame 3 Frame 4 Frame 6 Frame 1 Frame 2 Frame 3 Frame 4 Frame 5 Frame 1 Frame 2 Frame 3 Frame 4 Frame 5 Frame 6 Frame 2 Frame 3 Frame 4 Frame 5 Frame 6 Frame 1 Frame 3 Frame 4 Frame 5 Frame 6 Frame 1 Frame 2 Frame 4 Frame 5 Frame 6 Frame 1 Frame 2 Frame 3

Allow people in both direction (X-axis and Y when being arranged in the image for being used to create printing provided in this matrix Axis) on (pass through based on round or square lens array) and see cycle.Print image can also by providing per a line and Each row are so as to relative to other neighbouring row and columns slightly out-phase (out of phase), to generate less distortion to not losing Very.Interleaving process based on the matrix then will be same as described above, to be obtained or generated by final interleaved files (also sometimes referred to as X-axis and Y-axis pixel file).

High quality is created in (printing for being used together with lens array shown in this article) in order to be printed in lenticule Image, on both axes, the optical interval of lens should be with plate-making (plate-making), draw a design (proof) or numeral output Equipment accurately matches.In other words, the quantity of the frame in both X-axis and Y-axis be multiplied by lens quantity should be equal to (in certain feelings Under condition, it is exactly equal to) DPI (dpi (dots per inch)) of the optical interval of the output equipments of lens.By the piece of lens array material The accurate lens LPI quantity that construction generates is so-called mechanical spacing, but is to rely on viewing distance, these cylindrical mirrors will be paid close attention to (focus on) different frequencies, it means that when the line number amount of the per inch to a certain frame is combined, there will be with it is every The mismatch of the cylindrical mirror quantity of inch.(be referred to as spacing test) therefore, it is possible to use calibration process come preferably determine to The accurate line number amount of set a distance and certain lenses plate or film are focused on for specific printing equipment per inch.

Differently say, X-axis frame count be multiplied by lens numbers (optical interval) should be equal to output equipment resolution ratio (this is right It should also be as being applicable in Y-axis).One challenge is the DPI generated during printing, even if well-designed, it is also possible to saturating with printing The optical interval of mirror mismatches.This may be due in roll web (web) or paper process deformation and/or due to the system of film Typical contraction or expansion in making and deformation.Even if accurately making film with the optical interval with output equipment to match, In printing film, due to all printing technologies (for example, flexographic printing (flexo), intaglio printing (gravure), tablet print Brush (offset), letterpress (letterpress), holography, embossing and filling etc.) in public cylinder deform, spacing It may significantly change.In addition, the deformation may bigger on the roll web of cylinder circumference or the repetition direction of paper.

Past is completed in conventional linear grating optical device using software tools such as Adobe Photoshop File is adjusted to be matched with DPI to target spacing, and the process is in it can be used for relatively good lens array It works in rectilinear lens good.However, (for example, in any direction in the lenticule used in array as discussed herein On lens to be provided more than 200LPI), using these traditional software tools or by simply allowing the breach in image Or setter is placed with being adjusted the result is that unsatisfactory, because there may be serious quality problems.It may The reason of these quality problems occur is can to work in some cases although matching the trial of resolution ratio, often The file of damage is created, in the file of damage, the non-exact residence of image slice is at them relative in the channel of lens array.

In addition, not occurring this problem when using thick lens array, but using lenticule battle array as taught herein This is problem to be solved when row, because otherwise being mixed to viewer due to the light in channel, image may become unclear Clear or printing image can not may play the effect for obtaining desired 3D or movement effects completely.Such result is typically Due to the non-uniform image slice and in this process interpolation of file.When in use by breach or other traditional graph programs When checking file in a manner of microscope after the adjustment of progress, it can be seen that the slice of intertexture is no longer unified.Therefore, each figure As mixed relative to lens focus (for example, image can with another image blend (image 2 is mixed with image 4), It significantly reduces the quality for being provided to viewer or the image watched by viewer).Therefore, when in double X-axis and Y-axis, Quan Rong When considering this problem or challenge in the context that product interweaves, problem/challenge is notable complicated, and it can be special to export It is mixed and disorderly so that shown image makes us not pleasant, or even for viewer is impenetrable.

In some cases, desired optical interval can be (such as, the 3% of target in a certain range of target It is interior).In these cases, equipment (VMR (variable main scanning resolution ratio) such as, from Kodak etc.) can be used for file tune It is whole to arrive accurate number.However, since the process only works in an axis, so it is for X-axis as discussed herein It is not highly useful with Y-axis or total volume intertexture.In order to which image operates under the conditions of substantially any and is suitably adjusted With printing film, inventor, which recognizes, accurately to adjust spacing using other technologies/tool so that output equipment can be with It is run on both axes with father's resolution ratio (parent resolution), the figure to interweave without negatively affecting X-axis and Y-axis The integrality of picture.The objective optics spacing, as planned in file accurate of channel on two axis preferably relative to lens It keeps.Alternatively, by making file interweave on both axes with immediate integer, file can arrive number of targets by " scaling " Word.Such scaling can be executed on or below objective optics spacing, lead to DPI higher than target DPI or be less than target DPI.By manual software or automatic software, pixel can be added or subtracted in entire document image.

It was previously noted, in two directions, the number of frames used in combining image, which is multiplied by optical interval, to be equal to The accurate resolution of output equipment.This can be expressed as:NF x OP=DOR, wherein NF is number of frames, and OP is optical interval, And DOR is equipment output resolution ratio.A typical case in this respect is, despite the fact that be can select number of frames, but It is that number of frames is necessary for integer.In addition, the ring when lens numbers of per inch can be due to production batch and the printing of lens Border condition and change over time.As a result, making an option of above-mentioned equation normal work be, by choosing close enough obtain Obtain the integer amount and next pair of optical interval (even if not being required optical interval) of the frame of the accurate resolution of output equipment Image is combined.It is then possible to which so that the mode that spacing is able to adjust in the case where not changing resolution ratio is come to file It is corrected.

Due to the complexity of the process, it is saturating with this specification to provide how description successfully implements these technologies Exemplary (but non-limiting) process for the printing image that lens array is used together may be useful.For example, 2400DPI's is defeated Go out X-axis and Y-axis file that equipment can be used for printing combination, and the image printed is intended to and with 239.53 optical interval 240LPI lens (machinery) be used together.This means that with 240LPI that 10 frames are combined to obtain component (for example, anti-fake Device) required 2400DPI is desirable.Therefore, the challenge proposed is not change the size of file and do not losing How pixel integrality or in the case of not changing resolution ratio, be 239.53 by the Image Adjusting of the intertexture of 240LPI.

In order to carry out such adjustment, it may be useful to by the size of file amplification such as 0.196% (that is, according to 240.0 divided by 239.53), while also keeping identical pixel size.For this purpose, can be in the exact position of the width of entire file Place is inserted into the quantity of the calculating of pixel column.In this particular example, if file is 1 inch wide, this document has in total 2400 pixels.The example is followed, further, it would be desirable to be inserted into 5 (4.7 are rounded up to 5) a pixels to reduce intertexture LPI is counted, while keeping equal resolution or pixel size.Can implement in computer systems software routines (or intelligence calculate Method) (for example, software or code stored in memory can be executed by processor computer, to promote computer to storage In memory or processor/computer-accessible image file executes described function), effect is in non-warping figure Suitable place is selected as in the case of to add or clone pixel or the required amount of pixel column of removal.

Figure 10 is provided the image 1010 that is provided by original combined (or twin shaft) printed text is shown and is adjusted after by same The image 1020 that one printed text is provided compares 1000 side by side.In this example, adjustment is by Adobe Photoshop 0.7% amplification carried out.Image compares 1000 and shows if using simple uniaxial or other traditional size adjustment technologies, Then how simple spacing adjustment can destroy pixel integrality.As will be understood that from Figure 10, the image 1020 after adjusting is not It is original (pristine) again, and the focus of the lens of array will likely generate blurred picture or simply not (simply Not) the image comprising target or desired visual effect (such as, 3D in two directions or movement).It is related to using one The adjustment for the amplification that axis carries out or the effect of the adjust automatically carried out by breach are to mix viewer in a non-uniform manner The image that may be viewed by.

For example, when the image for replicating or adjusting above-mentioned matrix using Adobe Photoshop or other automated procedures When, occur to mix the light of viewer.This is because pixel is no longer unified (uniform) on both axes.Therefore, The lens (for example, based on round or square lens) of array focus on (focus on) inconsistent number, and light Viewer is mixed.Viewer can receive the information below number " 1 " and " 4 " etc. in the same time, to replace sight All numbers of the person's of seeing reception " 3 ".View result or the image of display have the quality of difference.The height and width of pixel be no longer Reach good result required unified precise height and width, because each pixel may variation in printing image.Knot Fruit is that lens focus is in different images (rather than focusing on specific expected pixel), and image is no longer original, is being permitted In the case of more, what image not may be viewed by even.

Figure 11 and Figure 12 show be configured with lens array and print image using provide different motion effect, as use In two useful example components of the security devices of currency etc..Specifically, 1100 He of set of the figure in Figure 11 and Figure 12 1200 can be used for showing the lens array based on circle, hexagon, parallelogram or square with described herein Twin shaft intertexture/combination printing image it is combined when can how effectively be used for selected movement effects are provided.Part Complicated interleaving process of the ground due to providing pixel-map, (it can be by as security devices for component shown in Figure 11 and Figure 12 Applied to currency, Product labelling and other object/items) it is particularly useful, because they are very difficult to duplication.

In the diagram 1100 of Figure 11, show according to the plan view of the lens/image component of this specification or orthogonal View 1110.Viewer is able to observe that or watches tool, and there are two the original images of each row of different icons, wherein icon is all It is static or non-moving.In diagram or view 1120, by the component be tilted to the right or angled (angled) (for example, By or reach the angles etc. of 15 to 45 degree), and intertexture (one group of original image shown in view 1110 of the matrix of frame Different points of view (POV), such as similar to matrix shown in the figure 7) it is configured as promoting the row of different icons in phase negative side It moves up.For example, the row with padlock icon moves right, and logo/icon is moved to the left.On the contrary, in diagram or In view 1122, which is tilted to the left or angled (for example, by or reach the angles etc. of 15 to 45 degree), and frame The intertexture of matrix is configured as promoting the row of different icons to move in the opposite direction again.For example, the row of padlock icon can be with It is moved to the left, and logo/icon moves right simultaneously.In other words, when from different perspectives or viewpoint watches lens/printing Image (or ink layer) about first axle or vertical axis by component shown in view 1110 or security devices (for example, carry out pivot Turn) when, the image of printing is adapted to be the animation for providing original image.

Significantly, there is the component of the lens array for the ink layer for providing twin shaft interlaced video to carry in more than one directions For animation or movement.In diagram or view 1124, which is tilted upwards or angled (for example, by about component Second axis or trunnion axis pivot, by or reach the angles etc. of 15 to 45 degree), and the intertexture of the matrix of frame is (in view 1110 One group of different points of view (POV) of the original image shown, such as similar to matrix shown in the figure 7) it is configured as promoting The row of different icons moves (for example, all moving up) in a single direction.On the contrary, in diagram or view 1126, by this Component tilt down or it is angled (for example, about component trunnion axis by or reach the angles etc. of 15 to 45 degree), and frame The intertexture of matrix be configured as promoting the row of different icons to move in a single direction again (for example, all moving down). In other words, when from different perspectives or viewpoint watch lens/printing image (or ink layer) (for example, by shown in view 1110 Component or security devices pivoted about the second axis or trunnion axis) when, the image of printing is adapted to provide for the animation of original image.

In the diagram or view 1200 of Figure 12, the plan view of lens/image component according to this specification is shown Or orthogonal view 1210.Viewer is able to observe that or watches tool, and there are two the original images of each row of different icons, wherein Icon is all static or non-moving.In diagram or view 1220, which is tilted to the right or is at an angle of (for example, logical Cross or reach the angle etc. of 15 to 45 degree), and (one group of original image shown in view 1210 is or not the intertexture of the matrix of frame Same viewpoint (POV), such as similar to matrix shown in the figure 7) it is configured as promoting the row of different icons in single direction Upper (rather than in opposite direction as shown in the 1120 of Figure 11) is mobile.For example, when by component (or security devices) to Right deviation When oblique, the row with padlock icon and logo/icon all moves down.On the contrary, in diagram or view 1222, by the group Part is tilted to the left or angled (for example, by or reach the angles etc. of 15 to 45 degree), and the intertexture of the matrix of frame is configured To promote the row of different icons --- such as, upward --- mobile in a single direction again.In the embodiment show in figure 12, When from different perspectives or viewpoint watch lens/printing image (or ink layer) (for example, by component shown in view 1210 or Security devices are pivoted about first axle or vertical axis) when, the image of printing is adapted to provide for the animation of original image.As shown in the figure Animation can be on the lateral direction relative to pivotal orientation.

Significantly, as discussed relative to Figure 11, there is the lens array for the ink layer for providing twin shaft interlaced video Component provides animation or movement in more than one directions.In diagram or view 1224, which is tilted upwards or is tiltedly moved (for example, by the second axis or the trunnion axis pivot about component, by or reach the angles etc. of 15 to 45 degree), and the square of frame Intertexture (one group of different points of view (POV) of original image shown in view 1210, such as similar to shown in the figure 7 of battle array Matrix) be configured as promoting the row of different icons in single direction --- but the direction and the institute during leftward or rightward tilt It was found that direction it is different --- upper mobile (for example, all move right or roll).On the contrary, in diagram or view 1226, it will The component tilt down or it is angled (for example, about component trunnion axis by or reach the angles etc. of 15 to 45 degree), and The intertexture of the matrix of frame is configured as promoting the row of different icons to be moved or rolled in a single direction again (for example, complete It is all moved to the left).In other words, when from different perspectives or viewpoint watch lens/printing image (or ink layer) (for example, will regard Component or security devices shown in Figure 121 0 are pivoted about the second axis or trunnion axis) when, the image of printing is adapted to provide for original The animation of image.

Figure 13 show such as different positions or lead to component tilt or it is mobile to change visual angle for viewer and by Viewer can see one group of image or the view 1300 of another lens/printing image (ink layer) assembly.The component can be with It is taken based on the form of the array of the lenticule of circle, hexagon, parallelogram or square, the figure that covering twin shaft interweaves As (being printed on the flat surfaces at the back side of lens array or on substrate (for example, bank note, plastic clip, paper or plastic label Deng), lens array is attached later on it).Interlaced video is printed using printed text, and the printed text as begged for above Be generated by ground, with the matrixes of combined frames (for example, the single image obtained at the different POV relative to horizontal and vertical axis/ The set of 2 to 4 of scene or more frame) to provide pixel-map.

In fig. 13, image or view 1310 show the straight view or orthogonal view of component or security devices 1300, Image is logo in this example.When such as passing through the upward tilt component (trunnion axis about component shown in arrow 1321 Or first axle rotates up the planar module) when, image or view 1320 are visible viewer.As shown, view/ Image 1320 shows the additional information relative to the original image seen in view 1310, has such as been interlaced video text The mark of the main body (subject) of part or the bottom side of object.When such as by shown in arrow 1323 to right rotation or tilt component (planar module is rotated or tilted about vertical axis (for example, second orthogonal with the first axle of component or at least crosscutting axis)) When, another image or view 1322 are from viewer.More information or image are visible in view 1322, all in this way The mark of the main body of interlaced video file or the left side of other objects.

In addition, when component is rotated down or tilts 1325 (being rotated about trunnion axis or first axle), another regard is watched Figure or image 1324, and in the view 1324, present the information that do not see in other views, such as or mark or The top side of the object of other imagings.View or image 1326 provide more information or the part of target object, such as mark/mesh The right side of object is marked, and when 1327 component of vertical axis or the rotation of the second axis or inclination about component, view 1326 is can See.

Figure 14 shows another embodiment or realization method of the image component (or security devices) 1410 of lens/printing One group of view/image 1400.As shown in the image 1412 of view/display, from vertical with the front surface 1411 of component 1410 Or orthogonal viewpoint see component 1410 (with the frame square corresponding with the different images of scene/object from different points of view The microlens array as described herein placed in the twin shaft intertexture of battle array).In some embodiments, by being based on circle, six The outer surface of the array of the lens of side shape, parallelogram or square provides front surface 1411.As shown, viewer can be with See the background for including quiet (icon and padlock) state wallpaper pattern.Icons/images component can show in the plane of film It is very deep, and may be visible in each viewing angle (for example, when to the right or be tilted to the left component 1410 when, It is visible in view 1414,1416).However, pattern is superimposed in the plane of film, but as shown in view 1412 It is sightless (or only slightly visible) (but being that can see in view 1414 and 1416) when straight viewing.

View 1416 can be used for showing (being closed with shallow (shallow) angle tilt in component by the interlaced video of component 1410 Be slightly slanted or rotate to the left in vertical axis) when the display that is provided.When with shallow angle tilt (for example, reaching about 15 degree etc.) When, superposition pattern is only visible with black in the front surface 1411 of the region of the film near viewer or component 1410. (to the upper, lower, left, or right, or about vertical axis or trunnion axis the image of printing is configured such that on either side direction Rotary components 1410) be slightly slanted (for example, be less than about 15 degree) cause superposition pattern gradually to become visible (to show in this example Existing black).The pattern is to be apparent in icon or wallpaper pattern in the plane (or outer surface 1411 of component 1410) of film Top or " superposition " being covered in above icon or wallpaper pattern.

At shallow angle degree, it is superimposed first visible on the part of the film of viewer or component 1410.Work as component 1410 when being further inclined away from viewer's (angle for such as, reaching about 30 to 45 degree or bigger), more and more to be superimposed Pattern gradually becomes as it can be seen that until working as with pre-defined more extreme angle (for example, 45 to 60 relative to normal view 1412 The angle of degree or bigger) it is entirely superimposed when watching component 1410 via surface 1411 until pattern is visible.This can scheme See in 14 extreme angle view 1414, wherein about vertical axis to be greater than about 60 degree of (for example, to the right) rotary components 1410.In view 1414, there is icon (mark in this example in the whole surface 1411 of component/film 1410 And padlock) wallpaper pattern on, superposition pattern it is fully visible.

Figure 15 shows the component 1510 of another embodiment of this specification.Component 1510 can be configured to serve as antifake device Part or label, the print with main body/substrate, the twin shaft intertexture for providing the matrix with difference POV frames as discussed herein The ink layer of map brushing picture and for watch printing image the lens based on circle, hexagon, parallelogram or square Array.It, can be with for example, the component 1510 can be label (for example, 2 inches multiply 1 inch or the label of other sizes) On roll web during its manufacture by printing down (print down) on 1.125 inches of centers etc..Component 1510 includes preceding table Face or upper surface 1512 (for example, the thin lens array formed by transparent or at least translucent plastics or similar material), pass through The image that the front surface or upper surface can watch intertexture as shown in figure (is built using pixel-map teaching herein Image).Printing image may include as shown in white (or other colors) frame 1513, can be used for printing (for example, soft version Printing) bar code and/or human-readable text gap or white space, this can be offline or be added in being handled below (for example, passing through heat transfer printing).

Component/label 1510, which has, be specially designed to providing multiple images and effect so that it is more difficult to reproduce And viewer is allowed easily to verify the printing image of its authenticity.For example, 1516 (example of gray background is presented in printing image Such as, can be (for example, the flexographic printing) printed under surface), it can print or be layered (colored on the gray background 1516 And/or black) icon or symbol 1514,1517.Symbol 1517 may be used provides the second symbol or text wherein --- Such as, should be completely in boundary with display label 1510 is not forgery or true text (for example, " OK ") --- Boundary (for example, round) form.

Printed interlaced image can also include the device/portion for the authenticity for further allowing viewer's inspection tag 1510 Part.For example, magnifying glass image 1520 can be incorporated into the printing block for manufacturing component/label 1510, and show In the plane of surface 1512 or film.Can be in image 1520 --- such as under the mirror of the magnifying glass of image 1520 --- One or more icon/symbols 1523,1525 are provided.Then, printing image is configured such that when viewer passes through figure When the mirror region (glassarea) of picture 1520 is checked, icon 1523 is revealed as black and icon 1525 is revealed as blue, this can With these icons 1514,1517 of rest part for being from being apparent in label 1510, different colors is (for example, when in mirror image When 1520 times viewings, the color of these icons is inverted).In addition, icon 1523 under magnifying glass image 1520 and 1525 can be with It is revealed as dimensionally more bigger than correspondence wallpaper/background version of these icons 1514,1517.

Wallpaper icon 1530 can be designed as when component 1510 about first axle tilt (for example, to the left or to the right rotation/ Tilt component/label) when moved on opposite (or identical) direction, and when component 1510 about biaxial inclination (for example, upwards Or be rotated down/tilt component/label) when moved on identical (or opposite) direction.With some implementations of label 1510 Example is on the contrary, the corresponding icon/symbol 1523,1525 under magnifying glass image 1520 can be designed as and not under the mirror Those icons 1530 are differently moved.For example, when rotated about specific axis/tilt component 1510 when, in mirror image 1520 Under icon 1523,1525 can move together in a single direction, and icon 1530 is such as shown in arrow 1531 in phase negative side It moves up.

Figure 16 shows the system 1600 for the component for being adapted for manufacturing all security devices as described herein.System System 1600 includes having for executing code or software program to execute the imaging workstation of the processor 1612 of specific function 1610.Work station 1610 can take the operation for managing input and output device 1614, with the several of processor 1612 The form of any computer equipment, the input and output device such as allow the station 1610 operator watch and it is defeated Print controller can as shown in 1675 be delivered to as the data mapped and image-forming module 1620 uses to create by entering The equipment of 1680 printed text 1648.CPU 1612 also manages mapping and 1620 addressable memory 1630 of image-forming module.

Mapping and image-forming module 1620 execute the function useful when executing following function and process described herein:It is all Such as, it is used for from 1632 delta frame set 1640 of original image, frame matrix 1646 is created from these image collections 1640, and from frame Matrix 1646 generates two-way bitmap or printed text 1648 (that is, using printed text of pixel-map).For example, memory 1630 It can be used for storing original image 1632, which may include background 1634 and can be provided as wallpaper one Or multiple icon/symbols 1636 (for example, these elements can be layered in background 1634).

Module 1620 can be used for generating several frame set 1640 from original image 1632, and gather every in 1640 One may include 2 to 10 of the different points of view from original image or more frames (for example, with reference to it is as shown in Figure 7, There is provided the frame set of the different POV frames (basic or original image 1632 X and Y-axis frame/image) along two axis).Module 1620 Frame matrix 1646 as described above can be generated suitably to map pixel, in order to provide with or without the suitable of movement effects When X and Y-axis interweave.According to matrix 1648, by that will have appropriate sequence (with all 3D and/or fortune in both direction Dynamic information, such as with the square with the data from matrix 1646 rather than striped) matrix 1646 row and column phase Combination, generates two-way pixel-map or printed text 1648.

Mapping and image-forming module 1620 can be based on various imaging/mapping parameters 1650 and generate printed text 1648.For example, It can be taken by module 1620:Including lens are the lens array design letters of circle, hexagon, parallelogram or square Breath 1652, optical interval 1654 and 1656 values of LPI are as input to create printed text 1648.Furthermore, it is possible to by module 1620 create printed text 1648, the quantity of the frame in all Tathagata setting set 1640 using equipment output resolution ratio 1670 Deng.Parameter 1650 can also include kinematic parameter 1660, such as to pass through the moving direction that icon/symbol is arranged and movement How soon occur and (need how much to rotate to realize special exercise effect etc.) to define how that inclination/rotation using component makes original Beginning image carries out animation.Parameter 1650 can also include color parameter 1666, such as with the image printed from file 1648 Component rotation in the case of icon/symbol whether change color and such color should be in the displayed image What.

Once creating printed text 1648, imaging workstation 1610 (in a wired or wireless fashion, can such as pass through number Word communication network) this document 1648 is transmitted to print controller 1680 (for example, another computer or computing device).Printing control Device 1682 processed can manufacture printing or embossing printing plate 1682 using the printed text 1648, and the printing or embossing printing plate then can For utilizing the surface of flat/back side of the embossing of manufacturing equipment 1684 such as lens array.Then the surface being embossed can To be filled using one or more coating/ink layers, to form the image component of lens array/printing (for example, antifake device Part) in printing image.Digital document 1670 can also be supplied to colored number by controller 1680 using printed text 1648 Word printing machine 1674, on the surface of the flat back side of such as lens array etc or lens array is answered later With thereon to provide to printing twin shaft interlaced video on the bank note of security devices of bank note/label or the side of Product labelling.

At this point, description can be by the mapping of such as Figure 16 and the software mould of image-forming module 1620 etc for executing The technology for the pixel adjustment that block/program (at least partly) executes may be useful.Figure 17 shows basis using flow The pixel method of adjustment 1700 of this specification.Method 1700 be included at 1710 (for example, using Figure 16 component 1680 to 1684) printing test is executed in the X-axis of lens array and also Y-axis, it as discussed above may be according to design with determination The optical interval being varied from.At 1720, (again in X-axis and Y-axis) selects desired or input viewing distance Target visual spacing.For example, as shown in 1730, method 1700 can be related to existing target spacing setting into for X-axis 416.88 and for Y-axis by target spacing be arranged 384.47.

Method 1700 is continued at 1740 with being interleaved X-axis and Y-axis in pixel-map.This is typically related to pair It is mapped (for example, 400 output is close in step 1730 place with the output of immediate equipment in desired target spacing The spacing of setting).In step 1750, method 1700 includes the difference between computing device output and objective optics spacing. In this example, the difference in X-axis be 4.22% (that is, 416.88 target spacing divided by 400 equipment output) and Y-axis on Difference be -3.9% (for example, 384.47 target spacing divided by 400 equipment output).

At step 1760, mapping and image-forming module/software program are used for based on the identified difference in step 1750 To remove pixel.In this example, module can in X-axis by removed particular for low information area 4.22% picture Element.Module can be also used for the pixel of the addition 3.9% in Y-axis.The step 1770 of method 1700 further illustrates this process, Wherein, module has the pixel of few information so that (for example, in this example in X-axis fifty-fifty) removes for identification, and can To execute the addition (for example, adding mixed pixel in Y-axis) of pixel by mixing the pixel near such as.At 1780, Printing plate is exported based on being modified to provide the printed text of pixel adjustment.It, can be in X-axis with 4800 in the Working Examples Pixel and the printing plate in Y-axis with the output of 4800 pixels for printing.At 1790, it is noted that for example due to differentiating again Rate original pixels, process 1700 keep the integrality of shown image without fuzzy.

Figure 18 can be used for being explained further the process that the twin shaft of the lens array for this specification interweaves that provides.It is looking squarely 1810 (its of lenslet array or lenslet for including four lens 1812,1814,1816 and 1818 is shown in figure or top view In, more typical array has more lens).As shown in 1815, in the non-limiting example lens 1812, 1814,1816 and 1818 be to be based on circular lens.In lens array 1810 in the following, can provide twin shaft printing image (or tool Have the ink layer of printing image), each frame 1813 in attached drawing is for indicating pixel.In addition, these " pixels " 1813 is each It is a to be considered lens focus.

The printing image provided with pixel 1813 provides when combined with lens array 1810 may be used to provide completely 3D images and the display equipment of multi-direction movement.For example, each lens 1812,1814,1816,1818 are displayed for following The image of ring.For this purpose, 45 degree of slope cyclic scannings are may be used to provide with the diagonal line set 1830 of the pixel shown in shade, and The horizontal and vertical set 1820 of the pixel shown with " star " may be used to provide edge to edge and upper and lower image cycle.

In consideration of it, chart 1850 is each to be printed on using twin shaft combination/interlaced video for illustrating how It is useful that 7 pixels presented below of mirror 1812,1814,1816 and 1818, which multiply the arrangement of 7 pixels to provide these effects,. In the example, four frames in X-axis are combined with four frames in Y-axis (for example, " X=3 " refers to four frames along X-axis A particular frame in set).Mapping and image-forming module (such as, module 1620) can be used for selecting frame appropriate to generate this The matrix of sample and/or printing mapping, and printed text can be generated from the mapping, for every shown in chart 1850 A pixel is come use when printing twin shaft interlaced video in order to provide using visual effect described in pixel 1820,1830.

Figure 19 to Figure 21 is the component shown for this specification --- for example, for combined with twin shaft interlaced video Lens array --- ray tracing drawing 1900,2000 and 2100.Specifically, Figure 19 is shown using as described herein The drawing 1900 of the tracking of the light 1920 of the component 1910 (for example, security devices) of ground configuration.As shown, component 1910 wraps Include ink layer/printing image 1916 that covering includes several 1918 (being interweaved using twin shaft makes 7 images intertextures) that interweaved based on The lens array 1912 of circular lens 1914.

It draws and 1900 shows from the idealization grating intertexture striped 1918 in printing image/ink layer 1916 and tracked Light 1920.Have modified the order of intertexture so that image suitably interweaves for viewer.In this example, Mei Getou The radius of mirror 1914 is 1.23 mils (mil), and lens 1914 are provided with 408LPI, and lens 1914 are 3 mil thicks, and are assumed Refractive index is 1.49.For the sake of clarity, zero width intertexture is only identified, wherein the 7 of the set of each two lens 1914 interweave 1918.It is tracked in the range of+30 degree to -30 degree, wherein showing close cylindrical mirror area with 5 degree of steppings.

Drawing 2000 is the solid ray tracing of the bigger overview for the drawing 1900 for showing Figure 19.The friendship of drawing 2000 It knits and is taken as that 2 mils are wide, the set of each two lens provides 7 intertextures.Five steppings often to interweave are tracked, range is to use 1 Spend+30 degree to -30 degree of stepping.The sequence of intertexture is 6,4,2,3,7,5 and 1.Drawing 2100 is to use normal interleaved order The tracking that (for example, 1,2,3,4,5,6 and 7) are completed, wherein the radius of lens is 1.23 mils, and lens are carried with 408LPI For lens thickness is 3 mils, and refractive index is 1.49.Lens width is chosen for 2 mils, and for two lens Each set provides 7 intertextures.The each lens of range spans for reusing+30 degree with 1 degree of stepping to -30 degree track five A stepping.In short, drawing 1900,2000 and 2100 shows the coding by making the by of having multiple interweave per multiple cylindrical mirrors complete And for the change of the distribution of viewer as obtained from changing interleaved order.

In the analysis lens array with twin shaft intertexture printing image of the invention in use, generating ray tracing and point Row figure is useful with array/graphical design of inspection program.At this point, Figure 22 is the drawing of Off-axis-light tracking 2200, and Figure 23 can be generated with the corresponding point range figure 2300 of array/graphical design of plan of analysis.In addition, Figure 24 Be with Figure 25 draw or point range figure 2400 and 2500 for being based on two of circular lens (or spherical lens) additional point ranges, and Figure 26 is the drawing 2600 for the ray tracing of lens associated with the drawing of Figure 24 and Figure 25.It is attached for this latter three Figure, the radiuses of lens are 5 units, and focal plane is about 10 units (for example, unit can be any list of such as mil Position).

Although the present invention is being describe and illustrated with a degree of specifics, it is understood that only passing through example Mode carry out the disclosure, and those skilled in the art can not depart from the essence such as hereinafter claimed invention Many changes are taken in the combination of part and arrangement in the case of god and range.

This specification teaches a kind of circle or square for including and having the ink layer of printing image/pattern combined The display module (for example, security devices) of the array of lens.Lens array by arrange as shown in the picture nested circle, six Side shape, parallelogram or square lens composition.In the middle printing image/pattern provided of ink layer (one or more layers) and thoroughly Lens array alignment (for example, being aligned with the X-axis of printing image and Y-axis), and image/graphics are printed by vertically and horizontally mapping Pixel (for example, using the twin shaft for the frame for defining matrix discussed in this article interweave (intertexture on two axis) printed text into Row printing) composition.Pixel can be any kind of, and usually be adapted to be output equipment and viewer on both axes Optical interval matched.Can lens array be provided with 200 or more LPI in two directions, in order to provide often putting down 4000 lens of square inch or more lens.The focal length of lens can change, but for based on round and square lens, some Array has been implemented with the focal length less than about 10/1000 inch.

The printing of twin shaft interlaced video for being used together with lens array, which can use, utilizes the printing text in generation One or more colors of the pixel-map provided in part execute.In some cases, diffractive technology is used for based on circle Lens array in interlaced video in either intentionally or unintentionally create with wavelength separation color.Specifically, print steps It is related to the printing of the file or pixel-map of the imaging of X and Y pixels, to generate printing block or digital picture, times among these One can be used for providing the ink layer with printing image/pattern (for example, being printed on the back side or the flat surfaces of lens material On, to provide the image of X and Y-axis pixel-map), with it is nested based on round and just in an array as described herein It is useful during rectangular lens are combined.In other cases, embossing printing plate is generated for lens material (lens array) The back side is embossed.Then, it fills the back surface of embossing with ink or is metallized to it in holography and based on circle Or the lens array of square is combined.But in some cases, printing can also be happened at lens array front surface or On contour surface.For example, printing can be related to top (that is, non-flat forms side of lens array) print characteristics directly in lens, Printing on color or image, with the back side or planar side of the lens for using interlaced video is combined.

Using the printing image of one of lens array by this specification viewing may be implemented many unique visions or Display effect.For example, the image mapping of X-axis and Y-axis can be executed so that when substrate (or component or security devices) to the left and to The wall of icon (for example, logo and padlock of exemplary drawings) is repeated when right bank (being rotated about vertical axis or first axle) Paper array rolls on direction opposite each other across substrate or mobile, and when substrate tilts up and down (about with first The crosscutting trunnion axis of axis or the second axis rotation) when it is described repeat icon wallpaper array in the same direction across substrate roll or It is mobile.This effect can be marked as " the non-individual body movement in opposite direction ".

In other cases, image mapping is executed so that when component/device repeats the wall of icon to the left and when being tilted to the right Paper array is moved or rolled (icon all moves in the same direction) up and down across the surface of component/security devices;And And when component/device tilts up and down repeat icon wallpaper array across the surface of component/security devices to the right and (again, icon all moves in the same direction) is moved to the left or rolled (for example, being tilted to the left so that all icons scroll up It is dynamic or mobile, it is tilted to the right so that all icons scroll down through, inclination is so that all icons scroll right, and dip down upwards Tiltedly so that all icons roll to the left).This effect can be marked as " the non-individual body movement on orthogonal direction ".

The image mapping of X and Y-axis pixel can be executed so that volume icon or image (for example, logo or symbol) There are five the sides (for example, top side, bottom side, left side, right side and positive side or front side) that may be viewed by for tool.It is tilted when with different instruction Or (orthogonal/normal view is tilted to the left, is tilted to the right, tilting upwards and tilting down or positioning it rotary components/device Between) when, this five sides may be viewed by three dimensions, have apparent depth and full parallax.3D marks/symbol/icon is just Face can be the color different from side, more obvious 3D effect be created with this, and this effect can be referred to as " total volume 3D”。

The another effect that may be implemented by the mapping of the image of X-axis described herein and Y-axis, which provides, has another fold Add the wallpaper of the icon of pattern.It is then possible to provide superposition pattern in printed text and the printing image of result so that when Superposition pattern is hiding when watching component from certain POV (such as, normal POV), but is superimposed pattern (in film and wallpaper pattern Plane in) gradually become on the top of icon/symbol/mark of wallpaper it is more and more visible (such as, when from normal movement to When the angle of 30 to 60 degree, etc.).Furthermore, it is not required that entirely printing image provides single effect.On the contrary, printing can be used The different blocks of image or part provide different visual effect (for example, any effect described herein).

If equipment for drying can be used for realizing system and method discussed in this description.These devices include but unlimited In, digital computing system, microprocessor, application specific integrated circuit (ASIC), all-purpose computer, programmable controller and existing Field programmable gate array (FPGA), it is all these to may be collectively termed as herein " processor ".For example, in one embodiment In, signal processing can be incorporated to by embedded or separate processor by FPGA or ASIC or alternatively.Therefore, other realities It includes resident program instruction on a computer-readable medium to apply example, when realizing program instruction by such device so that institute Various embodiments can be realized by stating program instruction.Computer-readable medium includes any type of non-instantaneous physical computer storage Device equipment.The example of such physical computer memory equipment includes, but are not limited to card punch, disk or tape, optics Data-storage system, flash ROM (ROM), non-volatile ROM, programming ROM (PROM), erasable-programming ROM (E-PROM), random access memory (RAM) or the permanent of any other form, semipermanent or temporary storage storage System or equipment.Program instruction includes but not limited to the computer executed by computer system processor and hardware description language can It executes instruction, such as very high speed integrated circuit (VHSIC) hardware description language (VHDL).

It can be real using pixel-map technology combination microlens array described herein although Figure 11 to Figure 15 is shown Existing multiple effects, but it may be useful to discuss these unique effects in more detail at this time.Pixel-map (or twin shaft is handed over Knit) allow to generate the printed text with multiple pixels, the multiple pixel is respectively to allow the effect about one of two axis The specific purpose of activation be generated.In other words, the activation on 2 axis needs pixel-map taught herein, Huo Zhezhi It is enhanced by pixel-map taught herein less." effect " that can be realized (is included in shown in Figure 11 to Figure 15 Those effects) it is considered and is realized on the single axis of the intertexture using grating lens and image in a single direction One group of effect it is identical.However, can once provide one in these effects in each direction using pixel-map now (or two, three or more), and security devices can use the arbitrary combination of these effects (in many cases, to exist An effect is provided on each direction).It (is another image or to repair by image modification that these effects, which include 3D, movement, overturning, The image changed), animation, ON/OFF (making image appearing and subsiding using about the rotation or utilization " activation " of axis), scaling, become Change (for example, overturning can still be watched to the transition of new images (transition)) and gamut (one as activation Divide to change color).

As the first example, can design and manufacture lens array and printing image component on an axis (such as in X On axis) 3D is provided, and effect activation is provided (such as, by Y-axis on the second (such as orthogonal) axis crosscutting with first axle Upper offer activation).Can be provided in the first axle of component in different layers pattern or element (such as, by making foreground Image is on one or more background images) 3D.It is then possible to the activation of additional effect is provided on the second axis, it is all Such as:(a) movement (for example, element moves in frame or has displacement);(b) overturn (for example, the overturning for two images, Image " A " changes into image " B ";Or more than two image can be used to provide for more overturning);(c) animation is (for example, frame Sequence can be used for describe or define image animation);(d) ON/OFF in frame (for example, can provide dependent on viewing Angle and the individual element or multiple elements appeared or disappeared);(e) scaling is (for example, can provide dependent on viewing angle and put The individual element or multiple elements of size that is big or reducing shown image);(f) transformation is (for example, effect can be similar from figure As the reversion of " A " to image " B ", but with the transition frames being included between final image so that viewer is it can be seen that from figure As " A " arrives the transformation of image " B ");And (g) gamut (for example, by multiple viewing angles or POV, individual element or multiple members Element can change color with the activation that the rotation by component may be triggered).

In view of these combinations, Figure 27 shows the view set 2700 from the different POV example components watched, In, the component as configured with lens array and print image with provide different movement effects (twin shaft activation) for currency Or the security devices of other objects are useful.In the diagram or view 2700 of Figure 27, show according to the saturating of this specification The plan view or orthogonal view 2710 of mirror/image component.Viewer is able to observe that or watches tool, and there are two different icons The original image of 2712 row, wherein icon 2712 is all static or non-moving.In addition, original image is included in and schemes The superimposed image or foreground image 2714A (being shown as hook labelled notation herein) shown in the different layer of row of mark 2712.Therefore, Component is adapted to be offer 3D effect.In the accompanying drawings, the row of two icons is shown, it is to be understood that this is intended merely to just In illustrating rather than as limitation.Understanding the row of two icons and how can make to be used to provide tool on both axes In the case of the safety for having activation, it will be appreciated that, each row may include that two or more different icons are (rather than every The single icon of row), and can include in assembly as needed third, 4th or more different icons row, to realize Desired display image.

In diagram or view 2720, component is made to be tilted to the right or be at an angle of (for example, passing through or reaching the angles of 15 to 45 degree Degree etc.), and the matrix of frame intertexture (one group of different points of view (POV) of original image shown in view 2710 --- such as Similar to the matrix being shown in FIG. 7 --- be used in pixel-map) be configured such that the row of different icons 2712 in phase Negative side moves up.For example, when component (or security devices) is tilted to the right, the row with padlock icon and/or mark 2712 To the left and move right.On the contrary, in diagram or view 1222, component is made to be tilted to the left or be at an angle of (for example, passing through or reaching The angle etc. of 15 to 45 degree), and the intertexture of the matrix of frame is configured such that the row of different icons again different from each other Moved on direction and on the direction opposite with view 2720 (icon 2712 to move right just now is moved to the left now, and And vice versa).

In embodiment shown in figure 27, when from different perspectives or viewpoint watch lens/printing image (or ink layer) When (for example, component or security devices shown in view 2710 are pivoted about first axle or vertical axis), printing image is adapted To provide the animation of original image.Animation as shown in the figure can be on the direction parallel with pivotal orientation.However, printed text It is configured such that such as foreground or some images of other tomographic images 2714A are maintained in identical relative position, and carries on the back This of scape or other layer of icon movement are (when these moving icons 2712 can be that foreground image and symbol/icon 2714A can be with When being provided in background layer) enhancing or even provide component 3D effect.

In addition, when activation component on another axis or the second axis in two quadrature axis, 3D effect can be with additional effect Fruit is combined.As shown, with present twin shaft interlaced video ink layer lens array component in one direction or Person provides animation and 3D effect when along an activation shaft, and provides in a second direction or when along the second activation shaft and turn over Turn (or transformation).In diagram or view 2724, component is made to tilt upwards or angled (for example, by the about the component Two axis or trunnion axis pivot, and pass through or reach the angle etc. of 15 to 45 degree), and the intertexture of the matrix of frame (is shown in view 2710 One group of different points of view (POV) of the original image gone out, such as similar to the matrix being shown in FIG. 7) it is configured such that icon 2712 retain identical or remain unchanged, and the symbol in other layers (foreground image)/icon 2714A overturnings (or transformation) to difference Image 2714B (here, hook labelled notation is turned into star).

Similarly, in diagram or view 2726, component is made to tilt down or be at an angle of (for example, the water about the component Flat axis, by or reach the angles etc. of 15 to 45 degree), and intertextures of the matrix of frame is configured such that the row guarantor of icon 2712 Hold static, and foreground or other layer of symbol/icon 2714A overturnings (or transformation) are different images 2714B (here, with component is worked as Identical image when tilting upwards).In other words, when component is rotated about the second axis (such as, about trunnion axis or X-axis), print Map brushing picture is adapted to be the overturning for providing image.The effect provided when being shown in FIG. 27 for being activated in a second direction The overturning of fruit, but effect can also be transformation, ON/OFF, movement, animation, scaling or gamut.

In order to further illustrate many possible combinations, Figure 28 shows regarding from the different POV example components watched Set of graphs 2800, wherein (twin shaft swashs the component to provide different movement effects with printing image as configured with lens array It is living) the security devices for currency or other objects be useful.In the diagram or view 2800 of Figure 28, basis is shown The plan view or orthogonal view 2810 of the lens/image component of this specification, and the component is configured to supply from not With the 3D (for example, floating and/or depth) of viewpoint and the identical or different pictorial element with Y-axis or X-axis activation is (to have Movement, overturning, transformation utilize effect other obtained by the intertexture of picture frame).Viewer is able to observe that or watches There are two the original images of the row of different icons 2812 for tool, wherein icon 2812 is all static or non-moving.In addition, former Beginning image be included in the first and second superimposed images shown in the layer different from the row of icon 2812 or foreground image 2814A and 2816A (is shown as word " OK " and hook symbol) herein.Therefore, component is adapted to be offer 3D effect.

In diagram or view 2820, component is made to tilt or be at an angle of upwards (for example, passing through or reaching the angles of 15 to 45 degree Degree etc.), and the matrix of frame intertexture (one group of different points of view (POV) of original image shown in view 2810 --- such as Similar to the matrix being shown in FIG. 7 --- be used in pixel-map) be configured such that the row of different icons 2812 in list It is moved on one direction (for example, all icons move down or shifted against with activation direction).In this movement of component In the case of (tilting upwards), foreground image 2814A and 2816A are remained unchanged (for example, not overturning at the moment).In symbol The movement of the icon 2812 of (or in the above in some embodiments), which strengthens, below 2814A, 2816A utilizes the component institute The 3D effect of realization.

On the contrary, in diagram or view 2822, make component tilt down or it is angled (for example, by or reach 15 to 45 The angle etc. of degree), and the intertexture of the matrix of frame be configured such that the rows of different icons again in a single direction (but this It is secondary upwards or with activation direction on the contrary) it is mobile.However at the same time, rollover effect is also activated, wherein foreground symbol/ Icon 2814A is turned to the image (for example, being turned to word " Yes " from word " OK ") as shown in 2814B, and other are accorded with Number/icon 2816A remains unchanged in this example.From view 2822 to view 2820, when symbol 2814B will change back or overturn When returning to image 2814A, overturning will occur again (for example, activating overturning using the rotation of trunnion axis or X-axis about component Effect, while there is the mobile effect for icon 2812 (in this non-limiting example in a single direction)).

In addition, when activation component on another axis or the second axis in two quadrature axis, 3D effect can be turned over additional Turn combination of effects.As shown, the component of the lens array with the ink layer that twin shaft interlaced video is presented is in one direction It is upper that animation and 3D effect are either provided when along an activation shaft and carried in a second direction or when along the second activation shaft For overturning (or transformation).In diagram or view 2824, component is made to be tilted to the left or be at an angle of (for example, by about the component The second axis or trunnion axis pivot, pass through or reach the angle etc. of 15 to 45 degree), and the intertexture (view 2810 of the matrix of frame Shown in original image one group of different points of view (POV), such as similar to the matrix being shown in FIG. 7) be configured such that Icon 2812 is placed in movement, wherein icon 2812 in the same direction (it is again, opposite with activation direction and its with The moving direction earlier of view 2820 and 2822 is orthogonal) it is mobile.Meanwhile symbol/icon in other layers (foreground image) 2814A (or 2814B) is remained unchanged, and symbol/icon 2816A is not overturn but is activated as with transform effect, in the transformation In effect, as shown in 2816B change into from be screwed into new position (for example, hook number in the example has new orientation, This may be considered as animation effect).

Similarly, in diagram or view 2826, component is made to be tilted to the right or be at an angle of (for example, the water about the component Flat axis passes through or reaches the angle etc. of 15 to 45 degree), and the intertexture of the matrix of frame is configured such that the row of icon 2812 again It is secondary that there is movement effects (being moved in same direction such as opposite with activation direction), and foreground or other layer of symbol/icon 2816A converts (or carrying out animation) to spin into image 2816B again.In other words, printing image, which is adapted to be offer, has profit The 3D of foreground image that can be overturn with activation, be converted or carry out animation, and can be independent of one another to this activation of effect And with background image independence.In addition, printing image provided for background image and meanwhile movement effects, which is shown To be activated as moving together on the single direction opposite with activation direction.It is moved on 2812 direction shown in of icon In the case of, the result is that depth effect (for example, 3D), wherein icon 2812 is revealed as from preceding shadow definer number/icon 2814A to 2816B It is pushed backwards.The effect can also with forwardly or outwardly to viewer push some layer it is combined.

In order to further illustrate that many possible combinations, Figure 29 are shown from the different POV example components watched View set 2900, wherein the component as configured with lens array and printing image to provide different movement effects (twin shafts Activation) the security devices for currency or other objects be useful.In the diagram or view 2900 of Figure 29, root is shown According to the plan view or orthogonal view 2910 of the lens/image component of this specification, and the component is configured to supply:Realize figure Second axis (such as Y of activation and identical or different pictorial element in the first axle (such as X-axis) of the orthogonal motion of pixel element Axis) on activation it is combined.Viewer is able to observe that or watches the original image for having the row there are two different icons 2912, Wherein, icon 2912 is all static or non-moving.In addition, original image is included in the layer different from the row of icon 2912 The first and second superimposed images or foreground image 2914A and 2916A shown (are shown as word " OK " and hook number symbol herein Number).Therefore, component is adapted to be offer 3D effect.

In diagram or view 2920, component is made to be tilted to the right or be at an angle of (for example, passing through or reaching the angles of 15 to 45 degree Degree etc.), and the matrix of frame intertexture (one group of different points of view (POV) of original image shown in view 2910 --- such as Similar to the matrix being shown in FIG. 7 --- be used in pixel-map) be configured such that the row of different icons 2912 in list It is moved on one direction (for example, all icons are moved down or orthogonally moved with activation direction).In this movement of component In the case of (being tilted to the right), foreground image 2914A and 2916A are remained unchanged (for example, not overturning at the moment).In symbol The movement of the icon 2912 of (or in the above in some embodiments), which strengthens, below 2914A, 2916A utilizes the component institute The 3D effect of realization.

On the contrary, in diagram or view 2922, make component be tilted to the left or it is angled (for example, by or reach 15 to 45 The angle etc. of degree), and the intertexture of the matrix of frame is configured such that the rows of different icons is (but current in a single direction again It is (opposite with movement shown in view 2920) and orthogonal with activation direction upwards) it is mobile.However at the same time, rollover effect Also it is activated, wherein foreground symbol/icon 2914A is turned to the image as shown in 2914B (for example, being turned over from word " OK " Go to word " Yes "), and other symbols/icon 2916A is remained unchanged in this example.From view 2922 to view 2920, when Symbol 2914B will change back or overturn when returning to image 2914A, and overturning will occur again (for example, using about the vertical of component The rotation of axis or Y-axis activates rollover effect, while having for icon 2912 (in single direction in the non-limiting example On) mobile effect).

In addition, when activation component on another axis or the second axis in two quadrature axis, 3D effect can be turned over additional Turn combination of effects.As shown, the component of the lens array with the ink layer that twin shaft interlaced video is presented is in one direction It is upper that animation and 3D effect are either provided when along an activation shaft and carried in a second direction or when along the second activation shaft For overturning (or deformation).In diagram or view 2924, component is made to tilt or be at an angle of (for example, by about the component upwards The second axis or it is horizontal pivot, pass through or reach the angle etc. of 15 to 45 degree), and the intertexture of the matrix of frame is (in view 2910 One group of different points of view (POV) of the original image shown, such as similar to the matrix being shown in FIG. 7) it is configured as making icon 2912 are placed in movement, wherein icon 2912 in the same direction (it is again, orthogonal with activation direction, can be at this It is shown in example to the right) mobile.Meanwhile the symbol in other layers (foreground image)/icon 2914A (or 2914B) is kept not Become, and symbol/icon 2916A is not overturn but is activated as with transform effect, in the transform effect, as shown in 2916B Ground changes into that (for example, hook number in the example has new orientation, this may be considered as animation effect from new position is screwed into Fruit).

Similarly, in diagram or view 2926, component is made to tilt down or be at an angle of (for example, the water about the component Flat axis passes through or reaches the angle etc. of 15 to 45 degree), and the intertexture of the matrix of frame is configured as making the row of icon 2912 again With movement effects (move in same direction such as to the left, and so as to activation direction (or the vertical axis or Y of component Axis) orthogonally move), and foreground or other layer of symbol/icon 2916A convert (or carrying out animation) to spin into image again 2916B。

Figure 30 is shown as can be on currency or another group useful with the security devices that currency etc. is used together Part 3010.Component 3010 could be formed with top or outer surface 3012, can be provided with lens array.Component 3010 may be used also To include (one or more) ink layer, provide using printed by the printed text with pixel-map as described herein Printing image activate (or activation of the image effect of 3D, movement etc.) to provide twin shaft on both axes.Specifically, The printing image of component 3010, which is adapted to be, allows viewing by multiple 3014 (such as, hooks shown in Figure 30 of smaller symbol/icon Number) composition background image.The printing image of component 3010 is further adapted to allow (by lens array/front surface layer 3012) Watch the foreground image being made of one or more symbol/icons (it is typically greater than foreground image elements 3014).

In some realization methods of component 3010, printing image is with by providing image in 2 or more layers Element 3014 and 3018 and the mode that provides complete 3D in all directions is mapped to the pixel of lens array.Such as institute in Figure 30 Show, the background image or pattern provided by symbol/icon 3014 is pushed backwards far from viewer, to be apparent in by symbol/figure Behind the foreground image of 3018 composition of mark.Element 3018 may be provided as larger element, and element 3108 may be such that It is revealed as floating in the different levels relative to pictorial element 3014 from all viewpoints.This can be by following come partly real It is existing:So that the remains stationary during twin shaft activation (about X-axis and Y-axis rotary components 3010) of image 3018, and simultaneously so that the back of the body Movement effects (are applied to pictorial element 3014) by the movement of scape image 3018.

Following other assemblies can be created:The other assemblies include being formed by printing figure using selected pixel-map As to provide the pattern or image that are activated in the first axle with listed herein or described any effect.In addition, print Map brushing picture can be configured as offer in second with any one listed or described effect (identical or different effect) The combination of the identical image element (for example, icon or symbol) or different images element that are activated on axis (for example, Y-axis).For example, effect Fruit can include but is not limited to:(a) 3D layered effects are (for example, pictorial element is shown as being apparent in different layers, wherein every A layer is flat image);(b) 3D true effects (for example, the picture or 3D elements by generations such as 3D softwares are provided);(c) it moves Effect (for example, moved in frame or the pictorial element with displacement);(d) rollover effect is (for example, turning over for two images Turn, image " A " changes into image " B ";Or more than two image can be used in rollover effect);(e) animation is (for example, retouch State or define the sequence of the frame of the animation for one or more pictorial elements);(f) ON/OFF effect (for example, dependent on for The viewing angle of component can make single or multiple pictorial elements appear or disappear);And (g) zooming effect (for example, rely on It, can be in the viewing angle of the printing image by the microlens array based on circle, hexagon, parallelogram or square Single or multiple pictorial elements are enlarged or reduced in terms of size).

Fig. 3 A to Fig. 4 B provide the lens institute shape based on circle and based on square for being used to form lens array At items example.In addition, these lens arrays are by specific pattern or arrangement, so as not to use the saturating of offset or nesting The row and column (for example, the lens in adjacent row and column are aligned rather than deviate) of mirror.The picture instructed herein by inventor The use of element mapping allows using the lens array with offset/nesting lenses and also to be configured as including hexagon lens Or the security devices with lens array/printing image component are effectively manufactured based on the lens array of hexagon lens.Cause This, Figure 31 and Figure 32 provide the specific works example of these realization methods.

In the embodiment shown in Figure 31, items 3100 label etc. of product (bank note) are provided with Security element Or device, the Security element or device are covering or are arranged on the saturating of the top for the ink layer 3120 for providing printing image The form of lens array (arrays of the lens based on hexagon) 3110.As shown, items 3100 include substrate or main body 3105, Such as cardboard or plastic plate (for example, to be used as the paper of currency or to be used for paper/plastics of Product labelling).Substrate/ On the surface of main body 305, image is printed via ink layer 3120, and lens array 3110 is arranged on ink layer 3120 (for example, ink layer 3120 and its pattern/image can be printed on substrate surface or lens array 3110 on exposed surface In back surfaces).

As indicated, lens array 3110 is made of multiple lens 3114, multiple lens 3114 respectively have adjacent ink layer The hexagonal base on 3120 surface, and with cheese cross section and/or a two or more sections (faclet)/ Side.Lens or round lens 3114 based on hexagon are disposed in multiple row 3112, and multiple row 3112 are such as by Figure 31 Parallel vertical axis or Y-axis 3113 (pass through row 3112 in lens 3114 center axis) shown in be parallel.In addition, lens 3114 are arranged as so that the lens pair 3114 in the adjacent column of row 3112 are in contact or at least close in base position.Further Ground, row 3112 vertically deviate so that the adjacent lens pair 3114 in particular column 3112 are spaced apart.Then, 3110 quilt of array It is configured to the parallel row with lens 3114, each lens abut their neighboring lens (or in pedestal in these rows Place is almost in contact with each other), it such as can be with by the parallel, horizontal axis or X-axis 3115 at the center of the lens 3114 in array 3110 See, and row is shown as adjacent to each other but also deviates (for example, having horizontal-shift and vertical shift.With this Mode, lens 3114 can closely be nested in pattern shown in Figure 31 (note that can with rotation array 3110, for Such as 90 degree of rotation so that " row " become " to go " and vice versa).

In the embodiment shown in Figure 32, items 3200 label etc. of product (bank note) are equipped with Security element Or device, the Security element or device are using the top of covering or the ink layer 3220 for being arranged on offer printing image The form of lens array (array based on circular lens) 3210.As shown, items 3200 include substrate or main body 3205, Such as scraps of paper or plastic sheet (for example, be used as the paper of currency or be used for paper/plastics of Product labelling).In substrate/main body On 305 surface, image is printed via ink layer 3220, and lens array 3210 is arranged on the exposure table of ink layer 3220 On face (for example, ink layer 3220 and its pattern/image can be printed onto on substrate surface or on the back side of lens array 3210).

As indicated, lens array 3210 is made of multiple lens 3214, multiple lens respectively have adjacent ink layer 3220 Surface circle or annular base, and with cheese cross section and/or a two or more section/side.It is round Lens 3214 are disposed in multiple row 3212, and multiple row 3212 such as (are passed through by parallel vertical axis in Figure 32 or Y-axis 3213 The axis at the center of the lens 3214 in row 3212) shown in be parallel.In addition, lens 3214 are arranged such that the phase of row 3212 Lens 3214 in adjacent column at least base position in contact with or close to.Further, row 3212 vertically deviate so that phase Adjacent lens 3214 in particular column 3212 be spaced apart.Then, array 3210 is configured with the parallel of lens 3214 Row, each lens abut their neighboring lens (or being almost in contact with each other in base position) in these rows, such as by wearing Cross the center of the lens 3214 in array 3210 parallel, horizontal axis or X-axis 3215 it can be seen that, and row be shown as that This is abutted and also offset is (for example, have horizontal-shift and vertical shift.In this way, lens 3214 can be closely It is nested in pattern shown in Figure 32 (note that can be with rotation array 3210, for such as 90 degree of rotation so that " row " Become " to go " and vice versa).

As discussed in the start-up portion of this document, moire pattern has been combined round and hexagon lens array and uses For many years.Typically, printing image is small fine image for the size of lens.In image some can with The lens of one to one dimension in two axis are printed compared to slightly more frequent or less frequent frequency, and in image Some can somewhat differently be printed relative to each other.The result is that using lens to viewer show the depth of field illusion or to Viewer shows the moire pattern of the movement of items.Typically, these and image are used in the anti-fake market of label and currency The combined lens array of printing.The thickness of lens be less than 5/1000 inch and down to about 0.5/1000 inch (for example, 125 microns to about 12 microns).The frequency of these lens is approximately per inch 400 × 400 to more than 1000 × 1000.

Although being useful on one point, the effect that can be realized using moire pattern is limited.For example, cannot clap 3D is shown according to and using moire pattern.Typically, moire pattern is in about 20 to 75 microns of focal length and an axis Per inch is more than in the very delicate lens of the frequency of 500 lens (or being more than 250,000 lens per square inch) In Safety Industry.In the case where microlens array is close nested (for example, as depicted in figs. 1 and 2), the printing under lens Image is typically 12,000DPI, and can be more than 25,000DPI.In other cases, these lens are more than in focal length In the case of 0.125 inch or even 0.25 inch per 30 lens of linear inch and per square inch only about 900 thoroughly Mirror can be pretty good.

It is reverse-engineering relatively easily to be carried out to them using a prominent question of moir é pattern.This holds very much Easily see the pattern under lens using cheap microscope and determines the frequency of image and pattern.In addition, lens can be cast Again it molds, this to forge.The relative difficulty of reverse-engineering comes from printing image, but this is also due to high score Resolution laser and placing device and become easier to realize.

Typically, lenticule is printed using embossing and filling technique.This usually makes printing be limited to a kind of color, this returns Because in the technique after a kind of color be easy automatic pollution the fact, and be also due to the technique be difficult to control embossing and filling Relative hue in printing technology to color spacing the fact.Have been realized in embossing-filling using a kind of color, high score Resolution printing Motion Technology, this attribution on the fact that:Roll web or paper flood coating by precreping, with ink and wipe Clean (in addition to embossed area) is wiped, and blade leaves ink residue and pollutant so that additional color becomes challenge.Phase General roll web is stretched and another mobile problem is, it is difficult due to the difference in terms of the running tension between color To realize for amplifying the required small optical interval difference of More.

Therefore, inventor determines, one kind is needed to be more difficult to replicate the anti counterfeit appts (if not can not reproducible).It is preferred that Ground determines that these equipment should also be designed to the open of the image for floating on focal plane and below focal plane (overt) " factor " shown.

The lens array of printing can be difficult to offset printing, intaglio printing, flexible version printing or any other method It is printed with paper or web-like form (especially web-like form).Some in problem are, make printing plate or " print The equipment of version placing device " and the physical capability of the very small point of printing or image.The fact that when and the register in equipment (registration) when inexactness, film stretching, extension and its combined dependent variable so that be printed in 4 color techniques or have Very high-resolution image needed for the microlens array of any true accuracy becomes or be difficult to carry out.These The fact, which is limited, can be done in printing lenticule.

General printing accuracy limitation found in printing machine handbook is it can be found that the following (set of color to color It is accurate):(1) best -8 microns of sheet-fed printing (Heidelberg is small gloomy);(2) best currency printing (the only paper of KBA Notsys ) -4 to 6 microns;(3) best roll web (intaglio plate or flexographic plate) -150 or more microns;(4) best center platen paper -50 Micron.In addition, to indicate substrate or lens array used in (safety and anti-fake required) thinner for physics, then for mesh It marks thickness and focal length relationship, lens array is finer or more small.Fundamental formular is as follows:(A) chord width=C;(B) the half of lens Diameter=R;(C) focal length=F (or lens thickness);And the lens numbers of (D) LPI=lens frequency or every linear inch.Then, Basic lens physics determines:R>.5(C).In addition, F=1.5 (C) (as approximation).

For example, can be with about 25 microns with the polychrome and plain color printing currency lines in pattern.Make it possible this Minimum reality LPI in both direction is about 1200LPI, and for proper 3D or animation, this needs at least five pixel.Therefore, 5 × 1200=6000DPI in two directions.However, better quality indicates 10 images and about 12000DPI.It can be with Non- registration pattern etc. is printed, to show movement and 3D with polychrome.However, for printing color to color, 4 color techniques or will be each Color together register the level registration requirements using past technology be impossible or at least extremely difficult realization.In this feelings Under condition, lens width or chord width (C) are about 21 microns.Due to needing a pixel for each frame, and for each lens 5 frames are needed, therefore are also difficult even for the print request of single color.Check above discussion, best web of printed Brush machine is with about 50 microns by color registration to color.(it is respectively 5 of 4.2 microns for 4 color techniques or with about 21 microns Frame) the registration requirements of other close polychrome techniques of chord width be about 2-3 microns.Unfortunately, this has been demonstrated to utilize mesh Preceding technology be difficult to, can not be attainable.

The non-holographic image in register is generated using current technology on an even axis using more than one color (to print Image) it is impossible.Obviously, it regardless of printing technology, moves or the photo of 3D is impossible below lens array. In roll web using the practice of present technology limitation be veritably be not present (thickness of material by necessarily more than 15/1000 " with Possible register color to color about 100LPI, and will not actually be wrapped in roll web).Therefore, printing and register Color is limited to individual offset printing of paper (sheet fed offset) technology (rather than being actually used in banknote or the label of safety).

The technology of beyond tradition printing is needed to solve the problems, such as a kind of this novel manner.There are the frequencies of little loss It in the microwave portions of spectrum, is balanced, the patterning on wavelet length scale and is perforated by the transmission and reflection characteristic that make surface Metallic film or film coated with metal realize spectral selection.For the critically important light frequency of Joule loss, (nothing is worn Hole) metallic film planar structure or successional violate the material alterations for being enough to provide or realizing reflectivity.Pass through design It, can be without using chemical substance, film coating or diffraction effect by loading or the geometry for the structure being embossing on surface In the case of greatly change " perceived " color of metal.

Continuous element of this novel frequency-selective effect based on (" intaglio " and " basse-taille ") pattern in Meta Materials The plasma Joule loss of part with both raised and recessed sections of specification configuration, and is specific for the opticator of frequency spectrum. Such technology has the advantages that the integrality of the metal structure in holding surface, and scalable technology and system for volume production It makes.

Highest possible resolution ratio for printing color image is determined by the diffraction limit of visible light.In order to reach this A " limit ", the spacing with 250nm (for example, less than the spacing of 10,000 nanometer (or 10 microns), are such as received 200 to 300 Rice range in or less than about the spacing of 300nm) individual color element (it is or is considered " pixel ") wanted Ask or it is expected to be used for so that effective printed resolution (being usually given as dpi (dots per inch) (DPI)) be about 100,000DPI (or 10, The range of 000 to 125,000DPI, or in some cases at least about 10,000DPI, and can be used extremely in the case of other Few 75,000DPI).Color information can be encoded in the dimensional parameters of metal Nano structure, so as to tune they it is equal from Sub-resonance determines the color of individual pixel.Such color mapping is generated with distinct heterochromia and fine color The image of modulation.This method can be printed for large volume color without ink by nano-imprint lithography.

The technology can be used for reproduce from different color to RGB mixing and CMYK primary colors (process color) can The entire frequency spectrum for seeing color, for the reproduction of photo or other images.It is important to note that it is different from diffraction image, from The obtained color of operation of the balance of back wave and transmitted wave is largely insensitive to viewing angle.Therefore, because knot It closes to be tuned to generate to simulate using the lens array described herein using both More and interlaced video and reaches 100, These nanostructures of the colour element of 000DPI result in the incident ray (due to lens focus) of different entry angle, The obtained color back to viewer is non-warping or changes, as the case where diffraction pattern.With focusing on individual The interlaced video of the lens of pixel or group pixels keeps design as former state and color when being presented or reflecting back into viewer It remains unchanged.Obtained color is not influenced largely by incident angle.

Lens array described herein and " plasma resonance " technology of being somebody's turn to do are combined to function such that into ideal due to the above reasons, Or at least highly useful combination for thin 4 color technique of film and for providing in safety, brand and other application The combination of the middle lens array used and register color.For the first time, can use can be in intaglio plate/basse-taille Meta Materials The color with fidelity effect generated in single step.It may be equally applicable for large volume and thin film surface, and can be with It realizes in single step technique.The mapping of pixel can be carried out after the intertexture or mapping of 3D or animated image.First may be used Image to be interleaved, and it then is converted into conversion method appropriate (continuous intaglio plate or basse-taille) in pixel scale, To simulate desired color.

It shows to be likely to occur by the conventional counterpart (the combined traditional printing with these lens) that will be 75 microns The example of feature and the surprising depth of animation.Even proof environment (image can not possibly carry out register and printing in production) In, it can be real for the maximum value of 6 images of the 400LPI lens (two-way based on round or square lens) of 6 images Now about 2400DPI.On the contrary, above-mentioned plasmon resonance system allow to design by provide 75 microns pixel it is very sharp Condenser lens.Primary colors, 62,500 views of straight color (PMS equivalents) or rgb color or picture frame are used to have 100,000DPI, which may be implemented 250 images, is multiplied by 250 picture patterns, rather than 6 are multiplied by (36 in lens, 6 frame patterns Image).Therefore, plasma resonance promotes the larger frame pattern that 6 patterns are multiplied by more than 6, and such as 7 are multiplied by 7 frame pattern (49 images Frame) it is multiplied by 250 frame patterns (62,500 picture frame) to 250.

Then by lens array casting, squeeze out or be laminated to the nanometer basse-taille comprising image or nanometer basse-taille structure or Stamping foil.The optical interval of lens can be designed and manufactured to match by the colour element of nanometer basse-taille structural generation Definite resonance or contrary circumstance.Existed by systematically removing and (being formed by the set of nanostructure) pixel set or addition (formulated) nanostructure planned in mixing (non-interference) color or pixel, optical interval can be scaled accurately Ground matches lens array so that the equipment cutting really of matching write-in file in the case where dropping to about 250 nanometers without interpolation Resolution.

Use the essence of plasma resonance or continuous metal frequency permission file for creating the image for using interleaved files The nano-pillar (nanopost) of fine control down to combination combines, to create color resonance in 250 Nano grades.The pixel " is replaced Change " indicate final pixel, and therefore, the adjustment for optical interval (image) to be matched to lenticule drops to about 250 and receives Rice.This is ideal for creating accurate matching between lenticule and image itself, because of its permission intense adjustment, and nothing Average and distortion the auxiliary program caused in file need to be used.

For the general intertexture of all lens arrays for using continuous metal frequency technique, can use photo, The Photoshop Illustrator or any amount of programs of Adobe companies create image in a normal way.Then lead to It crosses color-separated software (RGB or CMYK may be used for image) and color file is separated into color block.This is with very What high resolution ratio was completed, so that pixel can be decomposed so that color is established to be up to about 100,000DPI, wherein often About 250 nanometers of a pixel.Then the shape that the nano-pillar can be formed, with by it is Wavelength matched to electronics when given with the color Appropriate color is matched in the case of color associated plasma resonance.This can be completed in color-separated software.

Then will be construed to for the individual Colour selection of those pixels the suitable physical shape of micro-structure (nano-pillar) with Color appropriate is created to viewer.But before the final choice of shape, the size of file and/or lenticule is depended on, File is interleaved for down to the 3D and/or animation of one pixel of every frame or the possibility level of 250nm.Then file is carried out Interweave to match the either circle used in lens array, square, hexagon, linear, type of parallelogram still Non-spherical lens.Then pixel is explained using software, the software identification color and pixel and provide wound (after interleaving) Build data necessary to nano-pillar or micro-embossed file comprising X, Y and Z coordinate.

It is applied about lens and general manufacture, using interlaced video establishment file and is translating the file into embossing file Later, plastic base can be embossed and is then suitably metallized first, wherein used accurate super material Material is different according to application and changes.Material can be the combination of individual conductive material or conductive material, conductive material such as gold, Aluminium, silver etc..These materials can be coated with the layer of 2 to 50 or more nanometers of material with steam.On the contrary, film itself can precoat It is covered with Meta Materials and the rear embossing with nanostructure.

Can after the technique for metallizing and being embossed or even previously apply lens (again, can use it is any before Type/shape that face is mentioned).Part that can be on film or as film forms lens array and the hair that metallizes It is raw, and be then embossed on the planar side of lens.However, when hereafter apply lens when, be contemplated that adhesive and/or Sheet Metal Forming Technology and associated hotmelt and refractive index, to calculate focal length appropriate.

In short, the array of lens or lenticule:(1) it can be applied after the production of substrate, embossing and metallization; (2) it can be embossed in the case where being extruded first or cast lens array first, and then use nanometer intersection chart As being embossed (and then being metallized using Meta Materials);And (3) can be made on back side (planar side), metal Change and is then embossed.
